As part of an ongoing support contract to INMARSAT, Callisto provided manpower support to a LEOP being performed by Telespazio for the Apstar-7 satellite. Callisto provided support at the INMARSAT spacecraft control centre in London for the use of two of the Inmarsat ground stations (Bejing,China and Lake Cowichan, Canada) and the Inmarsat communication network. The launch was successful and the injection was as predicted and the ground stations provided support up until the drift phase.
